Struct miow::Overlapped [−][src]
pub struct Overlapped(_);
Expand description
A wrapper around OVERLAPPED
to provide “rustic” accessors and
initializers.
Implementations
Creates a new zeroed out instance of an overlapped I/O tracking state.
This is suitable for passing to methods which will then later get notified via an I/O Completion Port.
Creates a new Overlapped
with an initialized non-null hEvent
. The caller is
responsible for calling CloseHandle
on the hEvent
field of the returned
Overlapped
. The event is created with bManualReset
set to FALSE
, meaning after a
single thread waits on the event, it will be reset.
Creates a new Overlapped
function pointer from the underlying
OVERLAPPED
, wrapping in the “rusty” wrapper for working with
accessors.
Unsafety
This function doesn’t validate ptr
nor the lifetime of the returned
pointer at all, it’s recommended to use this method with extreme
caution.
Gain access to the raw underlying data
Sets the offset inside this overlapped structure.
Note that for I/O operations in general this only has meaning for I/O handles that are on a seeking device that supports the concept of an offset.
Sets the hEvent
field of this structure.
The event specified can be null.
